I loved this episode, a lot, for all the reasons you said; cool and original MOTW, sweet bro-mos, well written side characters (I adored Jesse and Cesar - I'm so happy they survived, I kept thinking one of them would die! And how refreshing is it that they got a happy ending, and out of the life, I almost don't want to see them again so that they can actually have it, but a selfish part of me wants them back, or for Sam and Dean to visit them and go horse riding!)

It sure seems like they're hinting that something is going to happen to Dean, especially since they teamed Sam up with Jesse here. But I'm all for a twist...I love twists!!!

Also when you said, "Hey, Dean, I know of a nice retirement village. Sam has the brochure." you forgot to add 'in his magical memory box of 100% adorableness!' :D
